A XLE STAND.

Appiieatidn inea June 24, 1920. serial No. 391,367.

To `@ZZ 'whom t concern; j *j j .Be Vit known that I," FRANK DanInLsoN, .a citizen of the United States, residing at Chicago7 inthe county of Cook and State of.

illinois, have invented .a certainnew an-d useful Improvement in Axle Stands7 0f which the following is a full7` clear, concisey and exact description, reference `being had `tothe jaccompanying` drawings, vforming a partof this specification. A. j

Th's invention relates to axle stands.

More particularly this invention relates `to provide a stand provided with jaws adapted to clamp an axlev housing between themfby the interpositionof suitable clamping blocksl so asVV to hold the housing while disassem` bling the saine.. y A j further purpose of the invention is to provide means' for holding the ring gear on the rear axle of motor/cars from turning when removing the bolts from the same and a still further purposeof the invention is to provide means for holdingthe' drive shaft from turning while workingthereon.

Other objects and advantages of the invention will appear as thedescription of the acompanying drawings proceeds, in which Fig. 1 is a front elevation of the improved.

axle stand, showing the same in position for forcing a gear on the axle;

Fig. 2 is a side elevation partly in section thereof; j

Fig. 3 is a fragmentary detail side eleva-` tional view of the clamping jaws of said stand arranged for forcing a gear off said axle;

Fig. llis a fragmentary detail front elevation of the clamping jaws and upper portion of the stand slightly modified showing a rear axle housing clamped therein;

Fig. 5 is a fragmentary .detail view partly in section on the line 5-5 of 4c;

Fig. 6 is a fragmentary detail viewfof cer tain portions of the device shown at the left Fig/Z visa similar view of certain portions of the device shown at ,the right of Fig-.11;` Fig. 8 is a front elevation yof thejaw nie'mf` bers ofthe improvedaxle stand showing thek same used as a straightening press; and

Fig. 9 is a side elevation thereof.. g Referring now in detail to the drawinws, theimproved axlel-jstand comprises,af base portion 10 and a fixed clamping member 111v secured tothe base. by bolts or any other sui-table means. VThe clampingmember 11 is providedy with an upwardly extendingfponV tion 12 provided with suitable guides 13 for a movable clamping member 14,k The Clamping member 14 is provided with-A clamping screw 15 free yto rotate in said, clamping member 14 and having screwthreadedfengagement with .the upper portion 12 of the clamping member 11. The upper end-iper-` tion of thefclamping screw 145is provided with a bloclr16 through vwhichyexteii'dsl a. bar 17 by means of which the clamping screw can be turned. Instead of using the bar 17 for turning thescrew, a,handwheel 18 as shown in Fig. at may be substituted.A --A transversejopeni-ng 19y is provided, inthe clamping member at `the upperv extremity thereof andthe openingl) isadapted toreceive a shaft 2O carrying slidablyathereonA f the movable supporting members21 and 22 which arek provided v.with suitablel eenL ters 23v and 24.; for holding an'v aXlek25 for any other member therebetween. The supporting members 21and 22 areprovided with handles 26 and 265. respectively and the handle26 is provided with an en-k larged end portion 27 that has 'an openingA 28 in one side thereof ,into which' projects'l the beveled edge portion 29.

Referring now to Fig. 7, it will-be noted that when the handle `member 26 is turned to 1 a horizontal position that the opening28 is.

adapted tol receive a ring gear 30, which isV part of thedifferential of an automobile' and is readily mounted on the rearaxle shaft 31. The beveled portion29 extends between two adjacent teeth on the gear 30 and {holds} the gear from turning on the shaft'whenit is desired to remove the bolts from the gear,v ,n

30, thus preventing the turning of the gear when the wrench is applied tothe head'ofy the bolts,it`being understood that the shaft 32v isclamped between the movable jaw '14s-M and thestationaryvfjaw 33,011 the jaw portion). fr

11 toholdtheisame.

AThe handle portion 26 has an enlargement 34 thereon which is provided with a square opening 35. i

Referring now to Fig. 6, it will be seen that this square opening 35 is adaptedlo receive the square end at the universal paint on the drive shaft 36 and thus prevents the same from turning, it being understood that the portion to the right in F ig. 6 of the drive shaft is clamped between the movable jaw 14 and the fixed jaw 33 to hold the shaft.. It will thus be seen that the drive shaft is clamped in position and held fromturning by this means so as to make it easy to operate thereon in making repairs and in assembling` and dis-assembling the parts co-operating therewith.

rllhe base portion 10 is provided with a pair of ears 37 extending outwardly from one side thereof and between these ears is pivoted a block 38 provided with an up wardly and rearwardly extending projection 39, the lower base of the block being adapted to rest on the upper edge of the ears 3? when in the position shown in full lines in Figs. 1 and 2.

When in the position shown in full lines in Figs. 1 and 2, the block 33 is adapted to receive the end portion 40 of the rear axle 41 when it is desired to force the gear into position thereon. In order to do this, the hollow cylindrical member 43 provided with a closed end wall 44 is mounted on the end of the shaft with its edge engaging the gear 42, the movable clamping jaw 14being moved upwardly far enough so that the member 43 can be placed between the same and the gear 42, the Q'ear 42 having previous-- ly been placed loosely on the shaft. Upon turning the screw 15 by means of the handle 17 so as to force the clamping jaw .14 outwardly towards the fixed aw 33, the cup-like member 43 is forced against the gear 42 and forces the same downwardly on the shaft until the upper end of the shaft strikes the end wall 44, the member 43 being so proportioned that the gear 42 will then be in its proper position.

When it is desired to remove the gear this can also be accomplished by the saine mechanism as above described by tilting` the block 38'to the dotted position shown in Fig. 2, by actuating the same by the foot beinO' applied to the extension 39. lt will be noted that the end of the shaft 40 is now tree to pass between the ears 37 as the block 38 is out of its path of movement. 'Villien this is true the hub 45 of the gear 42 will contact with the bottom of the recess 4t in the Xed aw portion 33, the shaft being otherwise free of the machine, merely being` guided by the opening 47 through the jaw and the opening 4S between the ears 37. fr piece of cylindrical shaft 49 or any other suitable member, is placed between the movrecense able jaw 14 and the end of the shaft 41. New when pressure is applied by means of the screw 15 to the jaw 14 to force the same downwardly, this will force the shaft 41 downwardly through the gear 42 and when the end of the shaft is flush with the upper surface of the gear, it will drop through the same and the gear will be free of the shaft.

In Figs. 4 and 5, another use for the clamping jaws is shown, the same being used in this instance to hold the rear aXle housing 50 so as to enable the two halves of the housing to be taken apart. ln order to do this, a block 51 is inserted between the housing` 50 and the liXed jaw 33. The block 51 and movable clamping block 14 are provided with oppositely directed beveled recesses 53 and 54 which provide wedge faces for tightly holding the axle housing 50.

ln Figs. 8 and 9 the axle stand is shown as being provided with certain attachments mounted in the jaws thereof, whereby the same is capable of being used as a straight ening press. ln order to use the device as a straightening press, a block 55 is mounted in the lower aw 33. rlhe block 55 is provided with movable supporting members 56 that have overhanging flanges 57, slidably embracing the block 55, so that the same can be adjusted longitudinally thereon. Mount* ed in the ll-shaped groove of the block 14 is a block 59 having a beveled port-ion 60 to seat in the groove in block 14. The blocl;` is provided with a curved face 61, facing toward the lower aw portion 33. ln order to straighten a shaft axle or any other mem ber G2, the member is placed between 'the jaws and resting on the members 56 and 59.

these being spaced suitable distance apart to properly straighten the member, depending upon the sharpness of the bend that is to be straightened. The screw 15 is then turned down and the shaft axle or other member 62 is straightened by the pressure exerted thereon. the rounded faces of the members 56 and 59 serving to prevent the formation of any sharp bends or kinks in the member 62, when the pressure is applied.

It will thus be seen that a machine has been provided that is capable of performing a .large number of different operations upon the rear axle, rear axle housing and drive shaft, of an automobile and that this machine takes the place of numerous machines heretofore necessary to perform these vari ous operations, resulting in considerable economy in the use of equipment and space in the shop.
